FRICTION-BUCKLE.

Specification of Letters Patent.

Patented Dec. 28, 19153..

Application filed May 3, 1915. Serial No. 25,539.

To all whom it may concern:

Be it known that we, JOHN J. BUCHANAN and JULIUs MALT BY, citizens of the United States, residing at Waterbury, in the county of New Haven and State of Connecticut, have invented a new and useful Improvement in Friction-Buckles; and we do hereby declare the following, when taken in connection with the accompanying drawings and the characters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this application, and rep resent, in-

Figure 1 a plan view of a friction-buckle constructed in accordance with our invention. Fig. 2 a reverse plan view thereof. Fig. 3 an edge view of the buckle as applied to a belt with the same under tension. Fig. 1- a corresponding view with the buckle in central longitudinal section. Fig. 5 a detached plan view of the buckle-frame. Fig. 6 a corresponding view of the buckle-lever. Fig. 7 a detached'view of the buckle in transverse section on the line w-b of Fig. 1, looking in the direction of the arrow 0.

This invention relates to an improved friction-buckle particularly adapted for use as a belt buckle, though not limited to such use, the object being to provide a simple, compact and effective buckle constructed with particular reference to thinness and to convenience in use in so far as it is adapted to secure a preliminary grip upon the strap, whatever its character and use, before the same is fully threaded through it.

With these ends in view, our invention consists of a friction-buckle having certain details of construction and combinations of parts as will be hereinafter described and pointed out in the claim.

In carrying out our invention as herein described, we employ a rectangular buckleframe struck up from a single piece of sheetmetal and comprising a front or grippingbar 2, a rear or tuck-bar 3, an outer intermediate or pivoting bar 4, an inner or intermediate or fastening-bar 5 and side bars 6 and 7, the said bars 2, 3, l and 5 being parallel with each other as are the bars 6 and 7 The outer edge of the grippingbar 2 is bent inward to form a gripping-edge 8 which virtually overhangs or extends beyond the outer or gripping-edge 9 of a narrow threading-slot 10 formed in a sheet-' metal buckle-lever 11 located on the inner slde of the outer portion of the said buckleframe and furnished at its inner end with integral leaf-like knuckles 12 which loosely embrace the respective ends of the pivotingbar 4 of the buckle-frame. The outer edge of the said lever 11 extends beyond the said bar 2, and hence beyond the outer end of the buckle-frame, as shown in 3 and l.

The fixed end 18 of a belt or other strap of whatever nature and purpose, is looped over the fastening-bar 5 of the buckle frame as clearly shown in Fig. 4 and fastened by stitches or other means. The free end 1a of the belt is passed from rear to front through the threading-slot 10 in the bucklelever 11, then outward over the gripping edge 9 of the said slot, and under and over the overhanging gripping-edge 8 of the gripping-bar 2 of the buckle-frame. The deflection grip or bight so obtained upon the free-end 14-, is sufficient to hold the same from slipping and give an opportunity to tuck the said end under the tuck-bar 3 of the buckle-frame, as shown in Figs. 3 and 4. Now any strain placed upon the belt or webbing will cause the buckle-frame and buckle-lever to assume the parallel positions shown in the said figures. When the buckleframe and buckle-lever assume parallel positions, as described, the gripping-edge 8 so overhangs the gripping-edge 9 that the belt or webbing is caused to form an acute angle 15 by means of which a strong grip is secured, the sharper the defection the greater being the holding power. By arranging the crossbars 4c and 5 on opposite sides of the transverse center of the buckle-frame and mounting the buckle-lever upon the intermediate pivoting-bar 4:, the action of the buckle is made extremely sensitive since the leverage is made very short. On account of the separation, in the manner described, of the bars 4 and 5, the knuckles 12 of the buckle-lever and the loop of the fixed end of the webbing, are separated so as to make the webbed buckle relatively thin, and therefore comfortable to wear, and neat in appearance. The construction described also reduces the amount of webbing, that must be used, to the minimum.

We claim 2- In a friction buckle, the combination with a buckle-frame having a gripping-bar at its front end, a tuck-bar at its rear end, a pivoting bar, a fastening bar, and two side bars, the said gripping, tuck and intermediate bars being parallel with each other as are also the said side bars, and the outer edge of the grippingbar being formed with an inwardly turned gripping-edge; of a bucklelever located upon the'inside of the outer portion of the said frame and having its inner end pivotally connected with the said pivoting bar and its outer end extending beyond the said gripping-bar of the frame,

and formed with a threading-slot the outer Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents,

edge of which forms a gripping-edge and is virtually over-hung by the gripping-edge of the gripping-bar.

In testimony whereof, we have signed this specification in the presence of two subscribing witnesses.
